I upgraded our community edition on Monday from the previous release dated 5/4/2016 to the latest release. I'm using observium to monitor the VM on which it is running, which is CentOS 6.
The context switches graph has gone from hovering around 3500 to about 4200 immediately after the upgrade. System interrupts have increased by about the same percentage, and System I/O and Load Average have bumped up slightly.
Are all of these typical of this upgrade? Nothing else was done to the system or to the devices being monitored. The increase in all these graphs (and a corresponding significant decrease in Observium performance) all correspond exactly in time to the upgrade.
I've been wondering why it's performing worse, and then I noticed these items. Just looking for ideas or any helpful suggestions, and if this is to be expected.
Thanks.
Bill
